I've got a fun @typescriptlang.org question... why can't TS be satisfied with this assignment? From what I can tell it is safe. www.typescriptlang.org/play/#code/G...

Literally just looking at pictures of my daughter from the school teacher, while an AI Agent works in the background. I have never felt like I had the time/energy/mental bandwidth to do this before.

terrific post, to which i'll add a couple of related thoughts. first: a lot of developers, especially juniors, tend to assume that other people's code is better than theirs, and so using a dependency (rather than a snippet) makes their codebase better this is very much not the case

some thoughts about the bloat introduced by edge-case first libraries

We recently ran a successful live failover of our control plane database from Azure West US to East US 2. Our goal was to validate that Vercel can survive a complete regional failure of its core database. Here's the full breakdown: vercel.com/blog/prepar...

At Vercel, our relationship with open source is foundational. Today we're sharing our Open SDK strategy, which is a commitment you can hold us to. vercel.com/blog/open-s...

I'm pleased to have had a small hand in this (all actual credit to @tomocchino.com). it is music to my ears — and, I hope, to open source maintainers and community alike... 🎶 specifically, I'm delighted that @vercel.com (and others) _see the value_ in aiming for openness, portability + choice.

me, a relentless refactorer webpro.nl/hire-me i have 1 or 2 days a week availability to untangle & fresh up any JavaScript or TypeScript codebase ✂️

Next.js 15.5 • Turbopack for builds (beta) • Node.js middleware (stable) • TypeScript support improvements • `next lint` command deprecation • Next.js 16 deprecation warnings nextjs.org/blog/next-15-5

Toronto friends!! 🇨🇦 We’re hiring someone to join us building the backend stack for an awesome open source platform for JavaScript developers! You can read more / apply here: www.vlt.sh/backend-engi... #nodejs #javascript

@e18e.dev CLI is available! Looking forward to trying it out!

Explained being On Call to my two year old daughter, so she has an intimate understanding of capitalism now. She wants to know who’s calling me, but otherwise seems ok with it.

Most annoying thing about SQL is that you can't chain WHERE clauses. Same annoyance as languages that don't allow trailing commas on lists.

Why does every system promote start with “you are an experienced software engineer”?

JSON is widely considered a machine readable format. It’s ironic that it became a standard precisely because it was human readable. And even more ironic that LLMs are reading plain text / natural language formats now.

Mind boggling that slackbot doesn’t an have LLM mode yet.

Every branch should automatically get a slack channel

Dropped @eslint.org in favor of @biomejs.dev in our 2 million LOC codebase. p99 ESLint times in CI went from ~19m down to ~2mins. A bunch of caveats, but we're...happy?

NuxtLabs, creators of Nuxt and Nitro, are joining Vercel. Same license, roadmap, and open governance, but now in a joint mission to build the best web.

Scope hoisting is broken in most JavaScript bundlers, and I'm considering removing it in Parcel v3. Wrote a post about why. devongovett.me/blog/scope-h...

I wonder if there's overlap between the people who're really good at writing clear prompts for coding tasks and the people who're really good at writing clear git commits. Seems that prompts could be seen as writing the commit first?

if you can, avoid exporting the types of a dependency. some of the migrations we've done are such a pain in terms of backwards compat because of this 😬

What do we say to incidents after a code freeze? Not today

What happened to conference hashtags

It should be a red flag if the most visited doc in your eng org is "how to force merge a PR"

A good reason to use node:test is that you can focus on upgrading your runtime, instead of upgrading dependencies.

Just casually deleted ~4000 branches from 2 repos at work. Happy Friday!

I've been doing @person mentions in @noteplan.bsky.social and now think that's a mistake. Switching to [[Person]] instead. Mean's I can't do folder nesting, but maybe that's fine. @stephango.com's guide using Obsidian recommends not really trying to organize notes either

Okta FastPass on mobile is so much better than the current flow

We removed GitHub’s merge queue and have doubled the number of PRs merged every week.

Nobody: "..." Security systems: Password confirmation is required every 14 days, and it's been 14 hours... so... toh-mayyy-toh toh-maaaa-toh

My favorite part of @vercel.com's weekly internal demo day is the zoom chat

after using cursor for a few days, I can confidently say I need a bigger screen and bigger text.

I'm stepping into a new role, which means this awesome opportunity could be yours! vercel.com/careers/engi...

@vercel.com is for curmudgeons

Notion needs pull requests

why isn't client/server called requestor/requested

ok fine, I'll walk a mile in your shoes, but I'm going to be hunched over looking at my phone the whole time

Local news outlets (government offices, schools, etc) just decided in 2012 that they would post their news on Facebook and never looked back. We need websites back again.

Just deployed esm-checker.fly.dev it can check the ESM readiness of any npm package 📦 I have lots of improvements in mind, and a npm package version to check a whole repo at once coming up 🎉
